To all whom it may concern:

Be it known that I, Mrs. FERDINAND ZI-IA MEL, ne'e CAMILLA Fnnnn, wldow,sub ect of the Kingdom of Hungary, and resident of Charlottenburg,nearBerlin, Germany, have made a'new Invention Referring to Production ofLighting Effects on Stages by Means of High-Tension Currents of HighFrequency, of which the following is a specification.

The present invention relates to a method for producing illuminatingefiiects on decorations and costumes, particularly theatricaldecorations and costumes, in which the illuminating effects are obtainedby means of electrical currents of high tension and of high frequency.

The articles such'as decorations or garments are impregnated withpulverized or finely divided metal such as metal powder, small balls,flakes, or the like, of good conducting material, such as copper,graphite, coal dust and the like. These articles thus prepared areintroduced into the circuit of the electric current or currents.Numerous sparks are thus produced between the several conductingportions of the articles.

For the reason of minimizing any danger, the electric current is chosenof a high fre- Specifieation of Letters Patent.

EFFECTS ON STAGES BY MEANS OF HIGH-TENSION CUR- RENTS OF HIGH FREQUENCY.

quency; and for the purpose of reducing the noise incident to producingilluminating effects to a minimum, the tension of the current orcurrents is also selected/high. The tension may vary within very widelimits, however I prefer a voltage of one hundred thousand to fivehundred thousand volts.

Having now described my invention, What I claim and desire to secure byLetters Patent of the United States is:

The method of producing lighting effects on stages by means of hightension currents of high frequency, which comprises impregnatingtheatrical garments or decorations with powdered conducting material,and thereupon introducing the articles thus prepared into the circuit ofhigh tension currents of high frequency, as and for the purposedescribed.

. In witness whereof I have hereunto signed my name this twenty-firstday of June one thousand nine hundred and nine in the presence of twosubscribing witnesses.
